So my local commuter train requires that folding bikes go in bags. I need to know who uses what. The Dahon El Bolso I've found for $55 but that seem like overkill especially for the Curve and since I don't plan to carry the bike anywhere other than up the escalator. I think I'm shooting for less function and more notional "cover".

Help me out here, the El Bolso somes with the Dahon Slip Cover? Is this the same slip cover that's sold separately for $20. I think the slip cover is what I want. Its advertized as folding down to paperback book size and simply covers the bike and uses a drawstring to close the bag.

If the El Bolso comes with it that might be nice to have but I'd never bring it with me on my daily commute. Probably only use it when camping or something.

What are your experiences? Worst case IMO is one of those mega big Target bags which I could compact down inside the under seat bag easily enough.
